The hydroboration of 6α- and 6β-hydroxyandrost-4-en-17-one is shown
to take place predominantly on the face of the
alkenetrans to the allylic hydroxy group. The
regiochemistry of the reaction is also modified with the formation of some
5β,6α,17β-trihydroxy-5β-androstane from
6α-hydroxyandrost-4-en-17-one. The structure of this tertiary alcohol
was established by X-ray crystallography.
